WINDOW CONSTRUCTION.

Application filed October 18, 1911.

T 0 all whom it may concern:

Be. it known that I. THOMAS H. CLARK, citizen of the United States,residing at Chicago. Illinois, have invented certain new and usefulImprovements in \l'indow Construction, of which the following is aspecifit'tltlOIl.

My present invention relates to improvements in means for securingtogether the members ((anprising the sash bars of metallic sashes forwindows. so that the panes of glass ma be held between said members.

The object of the invention is to provide a simple. strong, durable andetlieient construction capable of being readily assembled, and theinvention ineludes the novel features of construction ln-reinatterdescribed and pa"tieularl pointed out in the appended claims.

The invention is shown as embodied in a nulntin construction. and isillustrated in the aecou'panving drawings. in which: 1

l" r 1 represents a perspeetive detail sln win; the location. of theeross plates; Fig. 2 is a plan view partlr insertion: and Fig.2, asection on line 3--3l of Fig. '2.

ltel'erring by reference characters to this drawing. parts of the muntinare indieated at l and l. and may be made of au suitable metal.preterably galvanized ir n bent into the shape shown. The member l isprovided with a central raised :"ib l onoppositesidesof which the metalis curved outwardly as at l and then curved or doubled baeknpon itselfto form the glass holding portions of flanges l". The inner edges ofthese flanges are bent or turned at a sharp angle as indieated atl" tocooperate with the edges of the opposing member. The said opposingmember .2 has a main eurved body portion 2- with m wardly turnedportions or flanges 2. the edges of whieh are preferably turned bat-kupon themselves for stitl'ening or strengthew t 2" and being purposes?as iudieated a tween Wltlt'll edges the flanges l" ht. ll hen thetwomembers are assembled with the glass panes I. held therebetween asindieated in Fig. 3. the edges of the glass are elamped by the opposingflanges or faces 1 and 2". To provide for connecting the. two parts ormembers together in a simple and durable the members whieh constitutethe Patented Dec. 19, 1911.

manner, I provide a plurality of cross bars or plates 4 which have theirends resting in the s ce formed by the overturned portions forming theflanges 2", and these bars have their ends recessed or bifurcated, asindicated at 4. By striking down the metal of the flanges 2* into theserecessed or bifurated portions. as indicated at 5, the cross bars areheld firmly in position transversely of the sheet metal frame bars, Thecross bars are provided with threaded openings for the reception ofscrews 6 which pass through corresponding openings in the companionframe member. and are screwed into the cross bars to draw the two partsfirmly together.

I claim as my invention:

1. In metallic window construction, a pair of hollow sheet metal membersadapted to clamp .the glass between them, cross barsearried by one ofsaid members and having recessed ends. the metal of said member beingstruck into engagement with said recessed ends. and securing devicesconnecting the other sash member with said cross bars, substantially asdescribed.

2. In metallie window construction. a pair of hollow sheet metal membersadapted to elamp the glass between them. cross bars carried by one ofsaid members and ha ring recessed ends. the metal of said member beingstruck into engagement with said reeessed ends. and screws passingthrough the other member and engaging the cross bars.

3. In metallic. window construction a hollow sheet ,metal member avinginwardly turned spaced edges. torn. 3 glass holding flanges. a secondhollow sheet metal member having oppos ng glass holding flanges anda'ngularly turned edges cooperating with the spaced edges of the firstmember. cross bars within the first named member having recesses engagedby projections from, said first member and screws passing through thesecond member and engaging said cross bar.

In testimony whereof. I atiix my signature in presence of two witnesses.
